Y APPARATUS FOR RING-SPINNING, DOUBLING, AND TWISTING lVlACI-IINIEIRY.v

Application led March 1,

To all whom #may concern.'

Be it known that I, THOMAS WHITEHEAD, a subject of the King of Great Britain, residing at 2T Gorse road, Blackpool, England, have invented certain new and useful Improvements in Apparatus for Bing-Spin-v ning, Doubling, and Twisting Machinery, of which the following is a specification.

This invention relates to driving apparatus for ring spinning, doubling and twisting machinery and has for its object to provide an improved drive for the tin rollers, to make each spindle and carrier independent of each other, to reduce vibration of the spindle rails and to facilitate the adjustment of the spindles and carriers.

According to this invention four tin rollers or other driving` drums are employed for two rows of spindles and carriers and toothed or friction wheels on two raising and lowering Ytin rollers intergear directly with one another and with two stationarily. mounted tin rollers through the intervention of gearing arranged permanently in gear with the wheels on the tin rollers by means of links. To reduce vibration of the spindle or lifter rails, the rollers appertaining to such rails havev no connection therewith but are mounted in a sliding frame to which an up and down motion is imparted by any appropriate mechanism, a cushioning device being applied to the bottom of the slide to diminish the blow on the central lifting arm caused by the high speed of the tin rollers.

In the accompanying drawings Figure l is an end view with one end frame partly broken awayr of a spinning frame provided with a compensating drive" in accordance withv this invention showinga method of mounting the rising and falling tin rollers, and Fig. 2 is a similar view' showing a slightly modified drive.

A, A indicate the spindles, B, B the carriers, A1 the tin rollers appertaining to the spindles and B1 the tin rollers appertaining to the carriers. The rollers A1 are mounted at each end in bearings on a movable frame a1. The rollers B1 are mounted at each end in bearings on a stationary rail Z). The latter is bolted to upright Aframes C which are bolted to the 'fra-mes C1 of the machine. rl`he movable frame a1 is bolted to two cross frames a which make a sliding t with the uprights C.

' their supporting rframes constitute a com-V plete unit which can be applied to existing-y ring frames. The rollers A1 maybe geared directv to the existing frame shaft, or 4they may be driven by an electric motor. Motion is transmitted to each slidingframe byk a lifting arm a2 centrally disposed on a shaft a3 carrying outer lifting'a-rms at' which support the usual lifter rods a5 appertaining j y to the spindle'or lifter'rails a6. These arms at are provided with counterbalance weights asvusual and the bottom crossfframes are' u advantageously provided with cushioning devicesrto diminish the blow, or vibration on the central lifting arms caused by thehigh speed of' theV rollers. n vthe example shown this cushioning device comprises a rod E slidably mounted in a bearing e on each bottom cross frame and having a spring e1 interposed between a head e2'on the plunger and the aforesaid bearing, a pin e3 or `other appropriatedevice being employed Vfor retain-V ing the lplunger in itsv bearing. Weights are used to counterbalance the weight'of the sliding frames and rollers. Owing to the lifting rollers being mounted on a frame that is independent of the spindle rails the` latter can be readily adjusted relatively to the rollers by the usual nuts a7. The bottom v rollersA1 are provided with two intergearing wheels A2, and the top rollers B, B1 are provided with two intergearing wheels B2. In the arrangement shown in Fig. l

two pairs of intergearingwheels D, D1 areV mounted in brackets or 'guards Z Z having projecting studs d1, cl2 to receive links cl3 which are retained in position on such studs by collars Z4 and are connectedrin like Inan-y ner at their other ends to shafts a2 and B2 respectively which appertain to the bottom tin rollers. Thev links cl3 are of such a length` as to permanently retain the wheels D, D1 in gear with the wheels on the `top and bottom rollers. By this arrangement when motion is imparted to one of the top rollers from any convenient source of power a continuous -driveistransmitted to all. the other rollers which is not affected in any way by the lifting and lowering of the bottom rollers, the intergearing pairs of wheels D` D1 swinging out or in on their respective links as the bottom` rollers are lifted orv lowered. The various intergearing wheels may `drive through frictional contact Vor through suitable teeth. In the modification shown in Fig. 2, the left hand pair of intergearing wheels is dispensed with.

Vhat I claim as my invention and desire to secure-by Letters Patent of theUnited States is y l l. In ring spinning, doubling and twisting machinery, the combination of two stationarily mounted driving drums7 two rising and falling driving `drums intergearing directly with one another and link supported gearing arranged permanently in gear with the stationarily and movably mounted drums.

2. In ring spinning, doubling and twisting machinery, the combination of two stationarily mounted driving drums intergearing directly with one another, two rising and falling driving drums intergearing directly with one another and link supported gearing arranged permanently in gear with the 'stationarily and movably mounted drums.

8. ln ring spinning, doubling and twisting machinery, the combination of two driving drumemo'unted at each end in bearings on a rail connected to Vtwo upri'ghts adapted to be bolted to the machine frame, two interoearino drivin drums mounted at each end in bearings on a frame thatis slidable on the said upright-s and link supported gearing arranged permanently in gear with the stationarily and movably mounted drums.

Il, in ring spinning, doubling and twisting machinery, the combination of two driving drums mounted at each end in bearings on a raii connected to two uprights adapted to be bolted to the machine frame, two intergearing driving drums mounted at each end in l'iear'ings on a frame that lis slidable on the said unrights, link supported gearing arranged ypermanently in gear with the stationarily and movably mounted drums, -a lifting arm 'for moi/*ing the `slidable frame and a cushioning device interposed between the lifting `arm and the rising and falling rollers.
